A beverage comprising water, phycocyanin and having a heavy metals content below a threshold amount, the beverage having a pH within a certain range and a minimum acceptable shelf life, by optimizing the steps in the production of the beverage, but without adding many chemical substances and without carrying out harsh chemical treatment on the natural substances. By the combined use of a phycocyanin obtained, for example, by ultrafiltration or by treatment under pressure, with sterile demineralized water, and mixing the other components separately from the bacteria and other contaminants, in an aseptic environment, it is possible to provide a beverage that has nutraceutical effects, with low heavy metals content, at a suitable pH, and with an extended shelf life.

A composition for use in the treatment and/or prevention of adverse side effects induced by an anti-cancer compound, said composition comprising an aqueous liquid extract, the aqueous liquid extract comprising Phycocyanin. The present invention also relates to the use of this aqueous liquid extract comprising Phycocyanin and optionally Spirulina polysaccharides, for the treatment and/or prevention of adverse side effects induced by an anti-cancer compound.

Indeed, Phycocyanin, thanks to its antioxidant effects, can reduce the undesirable side effects induced by an anti-cancer compound.
